Apple announced back in 2020 that it will fully transition from Intel chips to its custom silicon in two years. While the transition period was determined by the company itself. there is no progress bar to see the degree of transition. Now, a new report has been published which details that Apple would completely shift to its custom silicon by November 2022.

In his latest Power On newsletter, Mark Gurman shares that Apple will “barely hit its two-year timeline” when it comes to transitioning from Intel chips to its custom processors. At this point in time, we have only seen the M1 chip in the company's entry-level MacBook Air, MacBook Pro, Mac mini, 24-inch iMac, and the iPad Pro. Since the first Apple Silicon arrived in November of last year, the transition is expected to be completed by November 2022.
